Blender stopped opening for me on windows 10
Ok, so the best way to solve mysterious bugs like this is to divide and conquer. Basically try to isolate things that might cause it and run experiments that rule those things out. What you end up with at the end will be the issue. 

We can't really be of much help since this process requires access to the machine with the issue. But perhaps trying this method may help you.

So, you've mentioned you have an access violation? That, sadly for you, is the equivalent of announcing you've lost your needle in a particular haystack.

Something you could perhaps try is to run blender from the command line with some of its debugging options. For instance try

blender.exe --debug


There's no guarantee that you won't get a crash, but at this stage, its probably beneficial to try and gather more information that will narrow down where the problem is.
